I-MPROVEMENT IN BIRD-CAGES.

Specification formingpa-rt of Letters Patent No. 173,416, dated February 15, 1876 application filed October 8, 1875.

1'0 all Iwhom t may concern:

Be it known .that we, GEO. R. OSBORN, of East Orange, county lot' Essex and State of New Jersey, and BENJ. A. DRAY'roN, o t' New York, county of New York and State of New York, have invented a new and usef'nl Improvement in Bird-Cages; and we do hereby declare that the following is a full and eXact description thereof, to enable others to construct and use the same, reference being had to the accompanying drawing forming a part oftllis specih'cation.

The object of our invention is to suspend a bird-cage byan elastic medium, so that the movements of the bird within the cage will produce an e'ect similar to the branches cfa tree when a'bird aliglits thereon; and our invention consists, tirst, in attaching a spring to the body of the cage in a iXed vertical position; second, in attaching the spring to the cap or top plate of the cage; and, thirdly, in the special means -for securing the spring to the cap, hereinafter fully described and claimed. 3. y

In the drawing, Figure 1 shows a portion of the top of a cage with a spring attached, the parts heilig broken to show the details of construction. Fig. 2 shows a coiled spring and the top plate detached from the cage.

A represents the upper part of the body of a cage; B, the spring, c, the top plate or cap, having its edges turned up and inward to form a ange for securing the lower coil of d is a bolt, having an eyelet-head4 and ring-nut e, for securing the parts composing the top plate of the cage. f is an eyelet for embracing the ends ot the wires forming the body of the cage, the wires` being soldered or compressed within the external groove formed thereon.A g is a disk arranged within the cage, and through which the bolt d passes, forming a hearing for the nut e. h is a chain, which connects the upper end of the coil-spring with the bolt-head d. The object of this device is to limit the extension of the spring, and prevent its distending to such an extent as to fail to recover its elasticity.

We do not confine ourselves to the form of spring shown, as it is obvious that it may be formed in various shapes-was, for instance, upon a straight mandrel-and a strip of sheet metal may be used in preference to the round wire; or an elliptic form of spring may be substituted, and for appearance sake the several forms of springs may be covered by aspun sheet-metal shell. The conical coiled spring shown is preferred to present the best appearance. n

We are aware that a bird cage has been suspended by an elastic medium, and this,

therefore, we do not, broadly, claim; but we are not aware that a spring or elastic medium has been so applied as to maintain itself in a vertical position at all times, and which greatly facilitates the act of liaiiging the cage.

We claim as our invention- 1. A bird-cage provided with a suspendingspring attached to the body of the cage in a lixed vertical position, asshown.

2. The combination of the top plate or cap and a spring rigidly -attached thereto, for the purpose specified.

3. The top plate having the turned flange c, for securing the spring B, substantially as shown and described.
